ey-passenger-tweaks

This cookbook is an example that can be used to change the passenger worker count and
reconfigure passenger_monitor. In this case, we are reducing the worker count and
increasing the memory limit on passenger_monitor so that an app that has high memory
requirements can run without being killed for bloating.

Installation

Clone this repo, then copy this directory into your custom cookbooks directory.

Change the variables at the top of recipes/default.rb to match your app, desired
worker count and memory limits

Caveats

The syntax in this recipe is set to work with our cookbooks version >=1.1.116
if you are running any older version of the main cookbooks, then the memory_limit
variable in the recipe needs to be provided in bytes, not MB

This recipe is only made to work with a single app, as it's more of a proof of
concept. It could be tweaked to loop through each app when creating the cron tasks, but
it is not advisable to reduce worker count in a multi-app environment, as you may not
have enough workers to serve requests

You will restart Nginx twice on every Chef run with this recipe. If that is a problem
then you will need to investigate keep-filing nginx.conf and loading up a custom stack
config (maybe custom-stack.conf, rather than stack.conf)
